Embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to according to its embodiment of the ultrathin lens type compound lens of the aspheric surface that the utility model proposes glasses, structure, feature and effect thereof, describe in detail as after.
According to the ultrathin lens type compound lens of the utility model aspheric surface glasses, be the inside prism of substrate to be attached to form the lens type compound lens on the convex lens, the inward direction light that utilizes the inside prism of substrate to produce is turned back and is compensated the eyes set, thereby solve the problem of regulating, safeguard the normal physiological state of eyes with the set balance.
See also Fig. 1, shown in Figure 2, we can obtain corresponding prism degree by the heart that moves of optical mirror slip, and the prism degree on the different diopter, diverse location eyeglass point meets:
L＝Y*D
For example, the convex lens of one+300 degree, it can obtain 6 prism degrees to the central point direction when 2 centimetres of positions of distance optic center point; The concavees lens of one-300 degree, it can obtain 6 prism degrees from the central point outward direction when 2 centimetres of positions of distance optic center point.
See also Fig. 3 again, shown in Figure 4, we can manufacture and design common prism compound lens eyeglass according to the principle of common spectacles lens optical center being carried out horizontal displacement, and make the geometric center of this special lens have specific prism effect and dioptric effect.
As Fig. 3, the common heart eyeglass that moves shown in Figure 4 is made than being easier to, and it is also very accurate that parameter is controlled.But, so not only can bring the difficulty of eyeglass installation, but also make this glasses become very not attractive in appearance because this common local edge thickness that moves heart eyeglass can be very thick and inhomogeneously be usually expressed as that very thick another side is very thin on one side.
See also shown in Figure 5, the ultrathin lens type compound lens of the utility model aspheric surface glasses, designed the ultrathin lens type compound lens of a kind of aspheric surface eyeglass especially, this eyeglass is divided into three zones: the centre is standard light school district 5, and its upper surface is made of sphere; The outermost of eyeglass is marginarium 7, and its upper surface is made of sphere; Be aspheric surface nature zone of transition 6 between the standard light school district 5 of eyeglass and marginarium 7, its upper surface is made of smooth surface freely, and this surface couples together the smooth transition naturally of the upper surface of standard light school district 5 and marginarium 7;
The lower surface 70 of eyeglass is a complete surface, and it is made of sphere, and the axis of symmetry of this sphere 70 overlaps with the axis of symmetry of marginarium upper surface sphere 7, and the radius-of-curvature of this sphere 70 equates with the radius-of-curvature of marginarium upper surface sphere 7;
Be provided with an angle between the axis of symmetry of the upper surface sphere 5 of above-mentioned standard light school district and the axis of symmetry of lower surface sphere 70, to the scope of 60 degree, the radius-of-curvature of the upper surface sphere 5 of standard light school district and the radius-of-curvature of lower surface sphere 70 are unequal at 5 degree for this angle.
Obvious attenuate of this eyeglass and thickness relatively can be more even, and simultaneously, effective optical zone scope of all eyeglasses can both guarantee that more than 25 millimeters it is unaffected so just to have guaranteed substantially that eyeglass uses.The requirement that designs and produces of certain this eyeglass is very high, has sizable difficulty on manufacturing process.
Seeing also Fig. 6, shown in Figure 7, is a preferred embodiment of the ultrathin lens type compound lens of the utility model aspheric surface glasses:
A kind of brand-new anti-ageing comfort type presbyopia is corrected glasses, and its most important character is to pay close attention to eyes to look the adjusting of early work industry, converge like the spokes of a wheel at the hub/the set synchronized relation comprehensively.Not only utilize convex lens to compensate the adjusting deficiency of eyes, also adopt the built-in prism degree of brand-new arc to compensate or the balance consolidation function simultaneously.
Owing to adopted the designing technique of the ultrathin lens type compound lens of the utility model aspheric surface glasses, a plurality of targets such as " central area elasticity zoom, prism mate automatically and central point is desirable reset " have been realized, the optic center point of this brand-new optical mirror slip effectively is extended to for a high-quality stable optical adaptation zone, like this, not only effectively enlarged this visual zone of looking nearly glasses---as long as within 2.5 meters of vision, the same can both the reading like a cork and work also makes and thisly look nearly glasses and become the secondary qualified interpupillary distance glasses of exempting from simultaneously.
The adjusting compensation of 1 presbyopia and set compensation:
Presbyopia is the problem that a kind of regulating power aging gradually with age growth, physical function, eyes significantly descends.Presbyopia is exactly a kind of phenomenon of regulating power deficiency.
The relation that 2 prism application and interpupillary distance or interpupillary distance change:
Fig. 6 is the optical schematic diagram that presbyopia and common presbyopic glasses are corrected, and Fig. 7 is the diagram of the rectification compensation relationship of presbyopia situation, as shown in the figure:
L＝L1-L2＝50A/J1-50A/J2 (1)
In the formula: L is prism degree/angle of convergence, and L1 is the prism degree/angle of convergence under the normal reading distance state: L1=50A/JI; L2 is the prism degree/angle of convergence after the generation presbyopia situation: L2=50A/J2.Wherein: A is an interpupillary distance, the distance when JI is normal reading/reading near point, JI=33 centimetre.J2 is the reading distance/presbyopia near point after the generation presbyopia situation, J2=100/3-D.D is the diopter that presbyopia is regulated needs compensation.After simplifying following formula:
L＝0.5A*D (2)
As seen, the relation between presbyopia compensating prism degree and diopter and the interpupillary distance presents a kind of fairly simple funtcional relationship.
In addition, according to the P rule, we can realize by the displacement of optical centre in order to make common lenses have corresponding prism degree, concern as follows:
L＝Y*D (3)
By (2) and (3) so:
Y＝0.5A (4)
Like this, if we design and produce the presbyopia glasses for 6 centimetres according to interpupillary distance, then to move heart distance be 3 centimetres to the amount of movement of the optical centre of eyeglass.
But, if patient's actual interpupillary distance is not A, but A+A`, so,
L＝0.5(A+A`)*D＝Y`*D
Y`＝0.5(A+A`)＝Y+0.5A` (5)
By (5) formula as seen, lens type lens presbyopia glasses is fully synchronous variation relation.
Seeing also Fig. 8, Fig. 9, shown in Figure 10, is another preferred embodiment of the ultrathin lens type compound lens of the utility model aspheric surface glasses:
Lens type compound lens myopia glasses are a kind of state variation that will look early work when industry eyes states that become to look in the distance, and take exercise by looking in the distance and eliminate the environmental factor hidden danger that causes myopia, improve distant vision, integration or optimize the refraction of eye system mode and prevent and the bathomorphic special optical glasses of safe treatment.What therefore, control was near-sighted is effectively to change people to continue the situation of a large amount of close eye operations and effectively increase the exercise of looking in the distance at all.
These lens type compound lens myopia glasses are made up of the prism-type light quantum lens of a pair of particular design, and need look prism degree and the lens strength that light situation, eyeball parameter etc. decide lens design in strict accordance with the wearer.Myopia subtracts can guarantee to realize that various near-sighted situation children adjust to the real state of looking in the distance with the photosensitive system of eyes, the ciliary muscle and the set (eyes inward turning) of dioptric system seeing when near, form deprivation when fundamentally eliminate reading is avoided regulating, converge like the spokes of a wheel at the hub nervous and tired.
Fig. 8 is combination of lenses and the correlation function synoptic diagram that myopia subtracts, and Fig. 9 is the optical schematic diagram that myopia and common spectacles are corrected:
1 adolescent myopia is looked the adjusting compensation and set compensation when near:
2 look early work when industry prism uses relation with interpupillary distance (or interpupillary distance variation):
Figure 10 is the diagram of nearly rectification of looking of near-sighted situation and prism compensation relationship
As shown in the figure: L=50A/J
D`＝D-3
In the formula: L is the prism degree/angle of convergence under the normal reading distance state; A is an interpupillary distance, the distance when J is normal reading.
The relation that myopia is looked nearly between compensating prism degree and reading distance and the interpupillary distance presents a kind of fairly simple funtcional relationship.
In addition, according to the P rule, we can realize by the displacement of optical centre in order to make common lenses have corresponding prism degree, concern as follows:
L＝Y*D
Like this, if we suppose the myopia of one-4D, and be 33 centimetres according to 6 centimetres of interpupillary distances, reading distance and design and produce such myopia and look nearly reading treatment glasses that then the diopter of eyeglass is chosen as-1D, prism degree need compensate 9, and the amount of movement of optical centre (moving heart distance) is 9 centimetres.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in the scope that does not break away from technical solutions of the utility model, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solutions of the utility model content, foundation technical spirit of the present utility model is to above any simple modification that embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
